Pengaruh Penggunaan Ekstrak Daun Kersen (Muntingia Calabura L.) dan Daun Sirsak (Annona Muricata L.) sebagai Antioksidan terhadap Kualitas Kimia Daging Ayam Broiler

Abstract

Broiler chickens (Gallus domesticus) are homeothermic animals whose bodies are covered with feathers and do not have sweat glands. This makes it difficult for broiler chickens to dissipate body heat. The use of antioxidants can prevent free radical attacks caused by heat stress. Therefore, there is interest in using natural materials as antioxidants in broiler chickens. Muntingia calabura L. (kersen) and Annona muricata L. (soursop) are known as plants that function as antioxidants, especially in their leaves. The effect of kersen and soursop leaves in extract form as antioxidants was examined in an analysis of water content, protein content, and fat content in broiler chicken meat. The treatments used were 9% kersen leaf extract, 9% soursop leaf extract, a combination of 6% kersen leaf extract + 3% soursop leaf extract, and a combination of 3% kersen leaf extract + 6% soursop leaf extract. The results showed that the combination of 6% kersen leaf extract + 3% soursop leaf extract produced the highest average water content (77.93%), protein (20.77%), and fat (2.67%) analysis, and the lowest average water content (72.91%), protein (20.10%), and fat (0.81%) analysis. The best results were obtained with treatment P3, which used a combination of 9% kersen leaf extract and 6% soursop leaf extract.
